Little sister goes to a luxurious big penis school

What was not commonly realised was that girls were getting bigger and bigger penises as time went by.

Their penises not only grow but girls born later grow at a faster rate.

The girls who had tiny penises a decade ago got bigger as time went by until now they are almost as large as boys.

However the girls who developed penises five years ago grew penises which were close to a boy’s size almost right away and have grown to be significantly larger than the average boy’s penis by now.

The current crop of teenage girls is bigger than boys their age (about fourteen) within a month of the penis developing and continue to get bigger very fast.

The public is not aware of this, perhaps because the media and government don’t like to ask teenage girls about their penis size. Only a few unlucky teenage boys find how large teen girls are to their embarrassment. Most people assume girls have small penises if any.

Koboshi hid under a mat in the gym and gazed down through the large window at the swimming pool. He was horrified. He didn’t like girls having penises and it seemed clear that almost every girl in his class not only had them but were hung. He’d snuck into the gym to peek at the girls’ private swimming class. He’d being hoping to see some firm young breasts filing out swimsuits and he had but… But not one girl had that divine area of feminine flatness.

Every single one was packing a fat bulge running up, sideways or even wrapped in a little circle.

His favourite animes were nothing like this. In them all the girl were gentle and sweet and had nice flat panties areas. They didn’t have those… MONSTERS!

The worst thing wasn’t that the smallest girl there was twice as long flaccid as he was erect.

The worst thing was that his beloved sister Mika… his dear sweet little blonde haired (A few years ago she’d asked mom for one of those new hair color change procedures), angelic little Mika -chan had … the biggest babymaker of all!

The girls ran and dived and chatted and stretched with each other happily. Miss Konomochi the swim teacher had a bulge too though hers was much smaller than even the youngest girls.

Mika had started to develop when she was fourteen. She had been quite upset though sex education class had taught her that the majority of girls had penises now. She had hoped that she could have been a “true girl” like in fairy tales and in anime. She was shy and hoped that it would stay as small as possible and hid it from her brother. Unfortunately it grew and swelled by the week and one day after catching a glimpse of her big brothers winkie coming out of the bathroom realised she had gotten bigger than him. She felt terrible. She bound her flopper up with bandages and tight panties but as she grew it got tighter and tighter and more and more uncomfortable.

One day she was trying to avoid going to the beach and her brother told her he knew about her penis

“Mika. I… know about you have a thing. Everyone in class is talking about how yours is the biggest It’s ok. Lots of girls have them now. You should go out and not be embarrassed.”

“Oh. I’m sorry Oni-chan. It’s just it’s gotten so big…”

“Ha. Girl penises don’t count. Anyway my penis is growing very fast. Soon it will be so big that it will make yours seem like nothing at all”

This was a lie.

Koboshi’s penis had not grown much at all compared to Mika’s development.

He was not much smaller than average for a Japanese boy his age, but there was simply no comparison to his little sister’s long dangling flaccid meat. He had phimosis like an infant but after just a month of growing his three years junior sister’s cock head had filled out and whenever she got an erection her fat cock head immediately pushed the skin right back displaying the gorgeous full, ruby red head.

Mika started to get erections in school. She several centimetres bigger than any other girl

(And much, much bigger than the boys
